Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
WOOTT
This audio effect plugin enhances sounds by simultaneously compressing loud elements and amplifying quiet ones. It's designed to add massive proportions, aggressive edges, and bring out subtle details in audio, making it ideal for producers looking to add hype and excitement to their tracks.
- Triple band dynamics algorithm
- Simultaneous downwards and upwards compression
- Dedicated limiter per band
- AUv3 audio unit effect plugin
- Universal support (iOS and macOS)
- Multi-output capability
- Mono switch for low-band signal

WOOTT is an Audio Unit plugin (AUv3 audio effect) inspired by the infamous OTT sound. WOOTT uses a triple band dynamics algorithm with simultaneous downwards AND upwards compression, and adds a dedicated limiter to each band. So what's all that techno mumbojumbo good for? 1. First, it slams all the loud, dominant aspects of your sound 2. Next it blows up all the subtle quiet bits that were hiding below As a result, it's perfect for: - Blowing up average sounds to massive proportions - Giving an aggressive sharp edge to synthesizer filters - Bringing out subtle details and movement that would otherwise get lost in the mix (in a hamfisted way, though) - Dusting off old breakbeat samples and loops - Hyping specific aspects of your synth lines - Making generally boring things more interesting WOOTT features: - AUv3 audio unit effect plugin - Universal (all iPads and iPhones supported + MacOS M & Intel) - Runs in all your favorite AUv3 plugin hosts: Cubasis, AUM, Beatmaker 3, Nanostudio 2, Garageband, etc. - Multi-output (requires compatible host) for post-processing the individual bands - Low-resource, so stack as many of them as you like - "[WO]OTT all the things!" - Downwards *and* upwards compressors (a rare feature on conventional dynamics plugins) - Smart soft limiter per band, adapts to its own band's specific settings - Mono switch makes low-band signal monaural for an extra tight bass Note: this is not a subtle effect. If subtle and minimal are what you're after, this is not the droid you're looking for :-)

OSCILLOSCOPE & SPECTROGRAM is a powerful audio analyzer app and audio unit plugin KEY FEATURES - Run as both Audio Unit and standalone app - View up to three seconds of audio on the screen - Pause and scroll horizontally to browse back in time - Pinch to zoom in / zoom out - See both oscilloscope and spectrogram separately or overlayed together - Frequency trigger mode helps identify the precise frequency and MIDI note of sounds in the spectrogram - Stereo and mono views - Level based trigger mode has lookahead, pause, and zoom - XY mode shows stereo correlation - Automatically adjusts FFT size to fit zoom setting - Bark-frequency scale spectrogram shows nice detail at low and high frequencies - When zoomed in, the oscilloscope uses sinc upsampling to show you a close approximation of what actually outputs from your audio interface after digital to analog conversion, rather than just displaying raw audio samples. WHAT DOES THIS APP DO THAT OTHERS DO NOT? 1. Pause Button We can't emphasize enough how useful this is. You never have to worry about trying to catch short events that disappear quickly because you can watch the sounds go by slowly at a 3 second viewer scale, then just pause and scroll back if you missed something. When you get to the event you want to see you can pinch to zoom in right down to sub-sample level of detail, then zoom back out when you are done and zoom in on something else. This feature alone makes almost all other oscilloscope apps unnecessary because it means you can easily see ANYTHING that you need to see. 2. Frequency Identification Mode In frequency mode, when you touch the frequency scale on the right of the screen a blue line appears on the spectrogram. When you position the line above a specific frequency on the spectrogram, a panel on the left side of the screen displays the octave, note name, and MIDI number. You can then use the frequency timing oscilloscope to lock in on the exact pitch in cents so that you not only know which MIDI note that sound corresponds to but you know exactly how many cents sharp or flat. The ability to simultaneously see the frequency on the spectrogram and confirm it with precision on the oscilloscope allows you to quickly and easily identify musical pitches to a level of accuracy that have not seen anywhere else, not even in desktop software. 3. Trigger with Lookahead Almost every oscilloscope has a feature where it re-draws the screen each time the input signal level crosses a specified threshold. This is the main and most basic function of any oscilloscope. However, when setting the trigger at a high level to view the attack section of musical notes or drums, we miss the first part of the note. By using lookahead, this app allows you to see a few milliseconds BEFORE the trigger point so that you can see the whole sound you want to examine. 4. Carefully Designed Spectrogram In all spectrum analyzer displays, the upper end of the frequency scale is crowded, meaning that a single pixel corresponds to 10 or 20 frequencies in the frequency analysis. In many other analyzer apps one of two things occur: either 9 out of 10 frequencies in that upper range simply get ignored and disappear from the spectrogram display, or all 10 frequencies combine together to make the pixels in the upper range appear brighter than low frequency sounds of similar volume. This may seem like a technicality until you run a sine sweep or a 20 KHz tone through the analyzer and find that large sections of the input simply aren't displayed on the analyzer screen. Looking at these kinds of test signals on a spectrogram is the primary way that we test and evaluate the quality of audio effect plugins. If a spectrogram is to be of any real use as an analysis tool, it should do this right. Other spectrograms often mess up the lower frequencies too, either by making them take up too much space or by making them very pixelated. This spectrogram carefully avoids these problems.
